SPECIFICATION formingpart of Letters Patent No. 624,035, dated May 2, 1899.

Application filed July 16, 1898. Serial No. 686,130- (No model.)

To all whom, it may concern.-

Be it known that I, GEORGE S. H'UFF, a citizen of the United States, residing at Portland, in the county of Jay and State of Indiana, have invented certain new and useful Improvements in Oil-Cans; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improvementin hand-oilers having a forced feed; and its object is to provide a simple and efiective oiler having detachable parts and capable of holding liquid lubricant under strong pneumatic pressure, having effective valves of peculiar construction for retaining said lubricant in its compressed condition for any desired length of time, having a spring ejection-valve positive in action and securely seated by the outward pressure of the contents of the oiler, and having means foradjusting and for obtaining access to said oiler.

To these ends the invention consists in the novel construction and combination of parts hereinafter described and claimed, and illustrated in the accompanying drawings, in which Figure l is an elevation of the oiler. Fig. 2 is a vertical longitudinal section through the device with stem broken away. Fig. 3 is a central. horizontal section through the ejector-valve,-and Fig; 4 is a detailed view of the parts of said valve detached.

Referring to said figures by letters of reference, A is the body of the oiler, of any desired material, preferably copper, and is provided with a lower flat bottom ct and an upper or strengthening bottom a, as shown. Said body is provided near its lower end with a tube B, communicating therewith and secured at its other end to a pump 0, thereby creating a direct passage from the pump to the interior of receptacle A. Said tube B isprovided near its outer end with a suitable valve h, which serves to prevent all backward escape of the compressed liquid within the receptacle.

Pump 0 projects upward from the tube B and is secured near its upper end to the upper part of the body A by means of a metal bar or plate B A piston c and rod 0, of the ordinary construction, are provided, and a detachable cover 0 permits the ready withdrawal of the piston for repairs, the. While the pump has been shown as permanently fixed to the tube B and rod B it is obvious that it may, if desired, be detachably secured thereto in any suitable manner.

Within the center of the top of the body ortion A is secured a reinforce A as shown extending portion a to which is screwed or otherwise secured a valve-casing D, directly communicating with which is a tube E, the upper end of which is likewise secured by means of an air-tight joint to the reinforced centerA of the top of body A, and which projects downward to a point near the bottom of the body or receptacle and preferably on the side thereof farthest from the tube B. Said pipe E is provided with a screen or netting e,

which serves to strain the lubricant passing therethrough up into the pipe E.

Valve-casingD is preferably substantially cross-shaped in side elevation and is provided with adjacent upperand lower chambers dd,

separated by a central partition (1 as shown,

and communicating through the valve-seat D; The horizontally-extending cylindrical arms D D of the valve-casing are hollow, and. are adapted to receive and guide the valve-rod F. Said rod projects through arm D and is held in a horizontal position therein by means of a threaded cap f screwed into the outer end of said arm, and by a side partition f at the opposite end thereof. The

chamber formed thereby around rod F is preferably filled with suitable packing to prevent the oozing out or leaking of the oil during its passage through the discharge-pipe. Rod F passes through partition 01*, its valve F resting in a valve-seat formed in the far 5 ther side of the partition. Arm D projects outward from this point and is adapted to receive the valve when pressed inward, so as to permit the free passage of the fluid through the valve opening. Said arm is provided with a detachable end (1 which may be removed if it is desired to obtain access to the valve in order to clean or repair the same. Resting against eapf and encircling rod F, is a coiled spring W, the opposite end of which bears against a collar F adjustably secured to said rod F by means of a screwffl as shown. Said spring serves to keep valve F normally seated.

A discharge-pipe G of desired construction is screwed or otherwise secured upon the upper end of the valve-casing and communicatcs directly with the upper chamber (1 thereof.

In operation the body A is filled by pouring the lubricant through the opening in the top thereof, which is closed by a screwcap lI. \Vhen a desired quantity has been placed therein, the pump-piston is forced up and down, forcing the airinto body Athrough tube 1 The air will rise above the liquid, and all backward flow of the flu id is prevented by valve 1). W hen sutlicient pressure within body A has thus been obtained, the can is grasped by the pump, which serves as a handle, and a finger is brought to bear upon the knob on rod F. Upon pressing the same inward spring f is compressed and valve F is removed from its seat. Immedidiately the pressure of the air forces the oil down and up through the screen a into pipe E, thence to chamber (1 through the Valveopening into chamber (Z and out through the discharge-pipe G. The outflowof the liquid can be readily regulated by the amount of force exerted upon rod F, which immediately reseais itself upon removing all pressure. It will be noticed that all outward pressure of the contents of the body tends to force the valve more tightly against its seat, thus preventing the gradual escape of iluid which occurs in valves which depend upon a spring to overcome the internal pressure.

Another great advantage of this invention is the detachability of all working parts. \Vheucvcr it is desired to clean or repair a part of the valve or its casing, it may be readily detached and replaced without causing the slightest trouble. If desired, the pump may also be detachably secured to tube 13 and rod B in any suitable manner.

In the foregoing description I have shown the preferred form of my invention; but I do not limit myself thereto, as I am aware that modifications may be made therein without departing from the spirit or sacrificing the advantages thereof, and I therefore reserve the right to make suchehanges as fairly fall within the scope of my invention.

Having thus described myinvention, what I therefore claim as new, and desire to secure by Letters Patent thereon, is

1. In a hand-oiler, the combination of the valve-casing having an upper and a lower chamber separated by a central partition, a valve-rod slidably secured in a horizontal position in said casing by means of a cap and side partition, as shown, packing held between said cap and partition, a valve upon the inner end of said rod adapted to be seated in a valve-seat formed in said central partition, and be opened inwardly, a chamber, for the reception of said opened valve, having a removable cap, for the purpose described, and means for retaining said valve in a normally-closed position, consisting of a coiled spring upon said rod bearing between the cap and a collar adj ustably secured to said rod, all substantially as and for the purpose described.

2. A hand-oiler consisting of a body having a combined handle and pump communieating therewith by means of an automatic valved tube, an inlet for the reception of oil into said body, a valve-casing detachably secured to the reinforced center of the top of said body, a tube secured to said reinforced center and communicating with said casing, and projecting down into the body, having its lower end screened, as described, an upper and a lower chamber in said valve-casing separated by a central partition, ahorizontal valve-rod passing through said central partition and projecting into the lower chamber, a valve upon the inner end of said rod, a valve-seat therefor, a chamber for receiving said valve when open, a detachable cap for said chamber, a cap and a side partition for guiding the valve-rod into its proper position, packing ineasing said rod between the cap and side partition, a spring for normally seating the valve and tensioned by means of an adjustable collar on said rod, a button upon the outer end of said rod and adjacent to the handle, and a discharge-tube detachably secured to the valve easing, all substantially as and for the purpose described.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE S. IIUFF.
